I have a feeling if regen braking was capturing over 20% of kinetic energy that would normally be lost, then that number would be all over marketing everywhere.

You have to start it before driving to collect data, it's not always running. You export the data to an CSV file

Unfortunately the Journey Log doesn't give too many details, just total miles driven and the amount of energy consumed:



The details I can fill in are average consumption was 33.1 kWh per 100 miles, ambient temp is 90 F, average speed was 50 mph (all road, no freeway), AC was set to 68F and fan speed was set to 40 percent. Total cost to drive 5.08 miles was 0.19 cents. I'll have to find an app or possibly a device I can plug in that will do more detailed logging

The shilling of inferior products knows no bounds.

Your right of course. The sooner those slower, inferior and less efficient ICE products go away the better

Indeed, it seems like theres a ton of conjecture here without any factual data other than the original post.

I guess for me....what difference does it make give or take what the % is.... we have long know electric is way more efficient So what (to me) The most efficient way is not always the right way. We recently took trip out to Mont Tremblant north of Montreal...then to Quebec City. In Quebec they have a very extensive electric circuit network of charging, I couldn't help but think what a PITA it would be to charge en route. The time and energy and hassle is just not for me. We chose to take one of my 4 cylinder cars as its far more efficient than either of my SUVs. $175 to drive 1500 miles, although we did stop numerous times, about 15 minutes (entire trip) were allocated to fueling. Would I trade a more efficient EV motor for a less than efficient ICE? No, as time and convenience are far more important. This winter, we might return to the chalet town, this time it will be with 21 4R and full time 4WD (the most inefficient way to travel) as there is so much snow out there..

Here are some of the chargers in Quebec., we did see a few people living the dream as they were sitting at the benches waiting for their EV to charge..

But why? It's but one contributor to the overall efficiency and without context it's a meaningless data point because customers don't really know what would be a good percentage or bad percentage when it comes to energy recapture. The only thing that matters is how far the vehicle is going to get you per kWh of electricity. That can be easily and directly compared vehicle to vehicle, and it doesn't matter much how it got to that outcome, be it more efficient motors, battery management, energy recapture or whatever. The only thing that matters is the net result, and marketers know that.

Very beautiful country, I've always wanted to visit Quebec. I've driven through the Western side of the country (Vancouver), which is also very lovely

MT is propaganda-driven drivel now just like Car and Driver.

But I'm glad whatever works out.

My spouse's company is trying out EV vans with 100 mile ranges......in Georgia and Florida for testing. The 100 mile range is already a disaster, not to mention it doesn't get really cold in Georgia and Florida which will cut that about in half in the winter. All the drivers are byching about it like you wouldn't believe, right off the bat. The range isn't good enough.

All magazines/articles are propaganda...depending on the readers point of view . And what van is this that only has 100 miles range? All the new Vans and Trucks coming out are 300 to 500 miles ranges. Are those golf cart vans? . Even the Nissan Leaf has moved past the 200 mile range

Of course a van with a 100 miles range is going to be a disaster! I would say they picked the wrong van

Huggggge company. Massive. The use of vans is huge.

I will find out what they are.

Edit: Ford Transit

That's definitely not a van made for anything traveling outside of a city. That battery is smaller than the battery in my Polestar. If you look at the description on Ford's website, it's made to go from point A to the jobsite and back, in other words local travel. Not the correct van for any type of distances past 50 miles. It would work great for say someone who drops off Amazon packages or does other deliveries, or maybe services areas around the business (like a plumber, HVAC tech etc)
